I hate to tell you this, zubrag..... I d/l your new version, and I'm back to getting the error again, even directly under C:.

I did the changes to the script that you suggested before, and here's the output:
IECapt.exe http://www.animalcameras.com C:/thumbs/5fe38d055b37c3bb79104a13a0cfe5b9.jpg

Thumbnail Generation Error. Thumbnail not created.
It looks like there should be a picture in the folder, but there isn't, and it's giving me the Thumbnail Generation Error again.
Edit: It will still pull up the existing thumbnails that are in the folder from before, it just won't create any new ones. The folder is writeable.
